| Extraction protocol |
To prepare tissues for sequencing, samples were disrupted to single cell suspension by mechanically mincing the tissue, followed by enzymatic digestion with Collagenase V (1 mg/mL in RPMI, #C9263, Sigma-Aldrich) at 37°C for 30 min under constant shaking. After digestion, suspensions underwent serial filtration through 500 µm, 100 µm, and 40 µm mesh cell strainers. We then enriched for live cells using the MACS Dead Cell Removal Kit (#130-090-101, Miltenyi Biotec). The resulting single cell suspensions were brought to the University of Michigan Advanced Genomics Core for cDNA library preparation and sequencing.
Samples were run using 50-cycle paired-end reads on the HiSeq 4000 (Illumina) or NovaSeq 6000 (Illumina) to a depth of 100,000 reads.

| Description |
iKrasG12D;Trp53R172H/+ (Ptf1a-Cre;TetO-KrasG12D;Rosa26rtTa/+;Trp53R172H/+) mice were provided doxycycline chow (1.0 gm/kg, #F3949, Bio-Serv) to induce KrasG12D. Mice were aged to 14 weeks and then harvested (“14-week KrasG12D ON”) or remained on doxycycline chow to 15 weeks before being switched back to regular diet for an additional week before harvesting pancreata (“15-week KrasG12D ON + 1-week KrasG12D OFF”). 1 female mouse was sequenced in this submission.

| Data processing |
The University of Michigan Advanced Genomics Core performed processing and alignment of the raw data using Cell Ranger (versions 2.2.0-6.1.2 depending on date of sequencing) with default settings and an initial expected cell count of 10,000.
Assembly: mm10, mm10-2020-A, mm10-2020-A_EGFP, mm10-3.0.0, mm10-GFP-3.0.0
